I can see I did not offer enough good clues re
this new sound in my van since it returned from the shop.
Here's the best I can do:
Sound seems to be coming from the rear.
I have only heard the chirping when I am driving
& have not listened from the rear of the van.
Chirping seems to increase in speed with engine speed.
Van was just tuned up, among other things...
Front & rear brakes were done along with rotors.
Any ideas?
